RQM F3-2831-BI-IG-M

Complete assembly module with highest system efficiency, specifically designed and optimized for use in air handling units. Multi volute flow guiding device of galvanized sheet steel to increase pressure and static fan efficiency. Newly developed high performance impeller with optimized shape and highest efficiency, comprising six backward curved hollow section true aerofoil blades with real turbulence profile and rounded, inclined blade leading edges from impeller shroud to back plate, for optimal impact over the entire width of the blade. Aerodynamically and acoustically optimized with highest static efficiencies. Impeller made of high tensile sheet steel in an automated manufacturing process, robotic welding, degreased, iron phosphated and coated with a high quality epoxy-polyester mixed powder, fastened with a clamping bush to the shaft of the foot motor, balanced statically and dynamically according to DIN ISO 21940-11. System inlet cone made of galvanized sheet steel for optimal inflow to the impeller, equipped with flow measuring device IMV as a standard feature. Ultra premium motor with highly efficient permanent magnet technology and efficiency class IE5. Motor magnets without rare earth metals. Integrated drive (VFD), mounted on the motor support plate, optimally coordinated with the high performance impeller. Drive (VFD) preprogrammed, immediately ready for operation with signal 0 to 10 V. With Modbus interface. No shielded connection cable necessary.  The drive system is 100 % speed controllable. Prepared for easy floor, wall or ceiling mounting on inlet side. For operation with any arrangement of the axes. Performance data to DIN 24166  Class 1 (BS 848 Class "A")
